Detailed Description

template<size_t Size>
struct cds::intrusive::feldman_hashset::hash_size< Size >

Hash size option.

By default, the size of hash value is sizeof( hash_type ). Sometimes it is not correct, for example, for that 6-byte struct static_assert will be thrown:

struct key_type {
    uint32_t    key1;
    uint16_t    subkey;
};

static_assert( sizeof( key_type ) == 6, "Key type size mismatch" );

For that case you can specify hash_size explicitly.

Value 0 means sizeof( hash_type ).
